ACETYL'EN E-GAS o EN ERATO R.

SPECIFICATION forming part of Letters Patent NO. 724,281, dated March 31, 1903.

Application filed December 17, 19 0l. Serial No. 86,198. (No model.)

To all whom it may concern:

Be it known that I, NELSON GOODYEAR, a citizen of the United States, residing-at Flushing, Long Island, in the .State of NewYork, have invented certain new and useful Im provements in Generators for Acetylene and the Like, of which the following is a specification, (Case L,) accompanied by drawings.

The invention is applicable to various gas apparatus, and relates in part to the overflow device, in part to the flush-out device, and in part to the agitating device for stirring up the water or other liquid and the sediment or residuum, so that-in flushing outthe liquidthe sediment and residuum would be'c'arried freely out with it.

In its most complete form the invention consists of a combined overflow, flush-out, and agitating device in which the passageway for the water or liquid forms a liquid seal for the movable agitator and is provided with bearings for the said agitator.

In the drawings, which illustrate the preferred form of the invention as applied to a well-known form of acetylene-generator, Figure 1 is an outside view of such generator provided with theimprovement. Fig. 2shows the improvement and a portion of the wall of the water-tank of the generator,parts being shown in full and parts in central section through the overflow-pipe. Fig. 2 is a detail in section of one of the parts. Fig. 3 shows the combined overflow and agitator, omitting the flush-out connection or part.

The preferable form of the invention is illustrated in Figs. 1 and 2, which include a flushing-out attachment, while in Fig. 3 such flush-out is omitted.

Upon the exterior wall of the tank 2 are fixed lower and upper pipe-elbows 3 and 4, respectively. A vertical pipe 5 is fixed in these elbows. The lower elbow communicates with the tank by the passage-way or mouth 6, and the upper one has an outlet passage-way 7, leading from the upper end of the pipe 5 through the sleeve. The pipe 5 is made of such a length as to determine the maximum height of the liquid in the tank. Within the pipe 5 isa preferably square shaft 8, rotatably mounted by means of a screwbushing 9 in the upper elbow and a socketbearing 10 in the lower sleeve formed in the socket member 11, which, as shown in Fig. 2, is preferably made in the form of a screwplug. The lower end of the shaft passes through a square hole in and serves to turn the agitator blade or arm 12, extending horizontally from the shaft through the opening in the tank-wall for stirring up the body of residuum at the bottom of the tank. The shaft is provided at its upper end with a handle 13, by which it may be rotated.

In the device shown in Figs. 1 and 2 I have shown flushing-out means,consisting of a cook or faucet 14, mounted in a short section of pipe 15, fixed to pipe 5 at the lower part thereof. The cock is opened when it is desired to flush the tank.

The operation of the device shown in Figs. 1 and 2 is as follows: -When the tank is filled, the water will rise until it reaches the upper end of the pipe 5 and overflows. During the operation of the generator the water in the pipe 5 acts as a water seal or packing for the agitator. When it is desired to flush the tank, the cock 14 is opened and the agitator also rotated to stir up the residuum, whereupon the water and residuum will flow out through the pipe 15. The gas may follow the liquid as the level in the tank falls; but by reason of the height of the flush-out cock 14 above the opening or mouth 6 enough depth of water seal may be insured to entirely prevent the gas from entirely emptying the tank and blowing 0E through the flush-out. The height of the cook 14 may be varied, there* fore, to suit the pressure if any be maintained during the flushing out. Thus, also, the agitator is always water packed or sealed with-- out requiring packing-rings or special provision for it.

I claim as the novel and distinctive features of the invention the following:

1. In combination with the water-holding vessel, an overflow passage-way in cornmunication with the interior of thesaid vessel, and a revoluble agitator extending through the said passage-way andthe wall of the vessel and provided with bearings, the said over-v flow passage-way constituting a means of sealing the said agitator, for substantially the purposes set forth.

2. In combination with the water-holding vessel, an overflow passage-way in communication with the interior of the said vessel, an agitator extending through the said passageway and the wall of the vessel and provided with bearings, the said overflow passage-way constituting a means of sealing the said agitator, and a flush-out connection branching from the said passage-way, the said overflow, agitator and the flush-out connection all having the same opening or means of communication through the wall of the vessel, for substantially the purposes set forth.

3. In combination with the Water-holding vessel, a flush-out connection therefrom, and an agitating device extending through the wall of the vessel through the same opening with which the flush-out communicates, for substantially the purposes set forth.

4. In combination with the water-holding vessel and as a combined flush-out and overflow, an overflow-pipe in communication with the interior of the said vessel and a flushingout device secured to said overflow-pipe and in communication with the interior of the same, for substantially the purposes set forth.

5. In combination in gas apparatus and with aliquid-holding vessel, a combined overflow passage-way and flush-out connection therefor, the said flush-out connection rising to a height suificient to maintain a sealing column of liquid at all times, for substantially the purposes set forth.

6. In combination with a gas-generator, an overflow passage-wayand an agitator having a rotatable bearing in said passage-way, for substantially the purposes set forth.

7. In combination with a gas-generator, an overflow-pipe, a residuum-agitator extending into the generator, and an operating-shaft for said agitator in said overflow-pipe, for substantially the purposes set forth.

8. In combination with a gas-generator, a liquid-overflow pipe outside of the generator, a flush-out cook communicating with said pipe, and a residuum-agitator, substantially as set forth.

9. As an attachment for gas'generators, an overflow-pipe, a flush-out cock for said pipe, a residuum-agitator having an operating member for said agitator within said pipe, substantially as set forth.

10. As an attachment for gas-generators comprising a liquid-overflow pipe, a flush-out cock for said pipe, a residuum-agitator protruding from said pipe, and an operatingshaft for said agitator Within said overflow-pipe, substantially as set forth.
